nice spin on a classic. though, you kinda do push boxes around. there's a strange behaviour, that the boxes stay green, when you push them off the circles, especially when you push several boxes over the same circle, as they will all turn green, but the door won't open. other than that: i can see some potential there, especially when you embrace the bomberman-side of the game a bit more (like long blast radius that makes it part of the puzzle not to be bombed to death, or a fast paced multiplayer...)
